Just to let you know I downloaded and used the file from the link you provided but it did not work, I have since found other information and links to downloading the Graphics Rules file that are specifically related to Nvidia cards ( there are other download options for the Radeon and Intel graphics cards) and after 5 days of hell this has solved my problem and I am running sims 2 at the highest resolution/settings with almost perfect sim detail. The smooth edging in game options that had previously been greyed out is now back and usable :)
All the info and links to downloading the Graphics Rule file which is correct for your own brand of graphics card can be found from step 3 on the following link
